Description:

Abstract:

The Washington State Freight and Goods Transportation System (FGTS) is used to classify state highways, county roads and city streets according to the average annual gross truck tonnage they carry. The Washington State Department of Transportation (WSDOT), with the assistance of the Association of Washington Cities (AWC) and the County Road Administration Board (CRAB), updates the FGTS on a periodic basis.

Purpose:

The FGTS identifies the highways and roadways most heavily used by trucks and provides factual data to support funding for projects that improve conditions for freight transportation. This information also supports planning for pavement upgrades, traffic congestion management and other investment decisions.
The FGTS classifies roadways using five freight tonnage classifications, T-1 through T-5, as follows: T-1 more than 10 million tons per year, T-2 4 million to 10 million tons per year, T-3 300,000 to 4 million tons per year, T-4 100,000 to 300,000 tons per year, T-5 at least 20,000 tons in 60 days.
Washingtons Strategic Freight Corridors are those routes that carry four million or more gross tons of freight annually (T-1 and T-2). Tonnage values are derived from truck traffic count data that is converted into average weights by truck type.
Other planning documents and reports expand this analysis and can be accessed through the WSDOT Office of Freight Strategy and Policy, <http://www.wsdot.wa.gov/freight/FGTS/default.htm>.

Attribute values (T Classification, Weather Classification) are determined by WSDOT, the Association of Washington Cities (AWC), and the County Road Administration Board (CRAB).

Process_Step:

Process_Description:

An Excel spreadsheet containing state route identifiers and beginning and ending ARM values for freight classification segments along state highways was placed as an event theme using ESRI software and converted to a state route feature class.
Similar spreadsheets from the County Road Administration Board containing Mobility data (including freight classifications) was placed as event themes using ESRI software and the WSDOT Local Agency Public Roads (LAPR) dataset and converted to county feature classes.
Geometry segments contained in the LAPR for city freight route segments were extracted to a city freight route dataset.
These feature classes were merged and attributes added and updated to produce a statewide freight and goods dataset.
